Czapek’s Agar (CZA)- Composition, Principle, Preparation, Results, Uses


Czapek’s Agar (CZA) is a type of culture medium that is used to grow fungi and other microorganisms in the laboratory. It is also known as Czapek-Dox medium, named after its inventors, Czech botanist Friedrich Johann Franz Czapek and American chemist Arthur Wayland Dox. Czapek and Dox developed this medium to study the nitrogen metabolism and protein synthesis of plants. Later, it was found to be useful for isolating and identifying various fungi, especially those belonging to the genera Aspergillus, Penicillium, Paecilomyces, and Candida.
